Curious Little Sister

Greg had turned on the shower and was preparing to get in
when he realized he'd forgotten a fresh towel. Leaving the water running, he
left the bathroom and headed down the hallway to the linen closet. After poking
around for a suitably large towel, he closed the closet door and made his way
back the bathroom. He pushed open the partially closed door to find his little
sister April standing in front of the shower curtain. Her hand was holding the
end of it, as if about to draw it back. "What are you doing?" Greg
asked in puzzlement.

April jumped and turned toward her brother. Her cherubic
face was bright red, contrasted all the more by the yellow curls that cascaded
about her head. "Nothing," she replied with faux innocence. Greg
sighed. April was forever pulling pranks on him and teasing him. He wondered
what she was up to. Then a thought occurred to him.

"Were you trying to peek in on me?" Greg couldn't
help but smile. April was thirteen years old now and she was going to start
becoming curious about things. Greg remembered when he was around her age how
he used to peek into Mrs. Dodson's window down the street.

April smiled sweetly. The same smile she used when she
wanted something from their parents. "Maybe," she giggled. Greg wasn't sure why, but he
suddenly felt uncomfortable standing in front of his sister wearing only his
pajama bottoms.

"Okay. Why?" He asked.

April turned an even deeper shade of red and she began
biting her thumb. An annoying habit she had when she was nervous. He caught her
blue eyes roving over his exposed chest and thought they may have lingered a
few seconds at his groin. "Well," she began haltingly. "Lucy at
school said that:" April started giggling and Greg huffed impatiently. Then
something in his brain clicked and he remembered that Sarah Wagner had a little
sister named Lucy. Uh oh, he thought to himself. "Lucy said that Sarah
told her that you had a real big:dick." She whispered this last word as if
afraid of being overheard even though they were home alone this evening.

Now Greg felt himself blushing. He'd gone out with Sarah
Wagner a few nights ago. They were making out in his car on an old country
drive and things got pretty hot. He had Sarah in the back seat, her shirt open
and pants down, and when he took his cock out she freaked when she saw how big
it was. She screamed so much as he fucked her that his left ear still rang. He couldn't believe Sarah had told
her little sister Lucy about it.

"So you wanted to take a peek and see, huh?" Greg
asked April, who nodded in response. Greg was a little uncomfortable at the
thought of his little sister wanting to see his dick, but he also felt aroused
at the thought. He felt his prick twitch slightly inside his pajamas.

"Can I see?" April asked timidly. "I've never
seen a real one before."

April laughed. "Yeah, but they don't really show you
anything." She took a few steps toward him. The entire time the water had
still been running and the bathroom was filling up with steam. "Come on,
Greg. I told Lucy I'd find out and tell her."

"Well
tell her you saw it and it was fucking huge, alright?" Greg tried
to brush April off as he was becoming more and more uncomfortable. He'd noticed
his sister's nipples hardening beneath the tank top she was wearing and tried
not to look away from her eyes.

"What's the matter?" April asked teasingly. "Is
it really not that big at all?" She laughed.

Greg knew he was being baited but he didn't care. April was
starting to piss him off. "Alright, you little brat! You want to see my
cock, come over here and take my pants off!" He gave her a challenging
look. He was sure she'd back down.

Instead
April closed the distance between them and, grinning broadly, dropped to her
knees and pulled down Greg's pajama bottoms in one fluid motion. Greg
was too startled to speak or move. He simply stood there as his sister peered
at his exposed genitals. She screwed up her face and looked up at him. "It
doesn't look that big."

"Huh?" Greg asked stupidly. He looked down at
himself. His penis hung flaccidly, only two or so inches long, surrounded by a
tuft of dark, curly hair. His balls were contracted with nervousness, barely
visible amidst his pubic thatch. "Well I'm not hard!"

"Make it hard," she told him as she returned her
attention to the object of her curiosity.

"It's not that easy," replied defensively. His
head was spinning. He couldn't believe April was on her knees inches in front
of his exposed privates! God, what if mom and dad came home and found them?

"Can I touch it?" April asked. "Will that
make it bigger?" Greg stood mute, too shocked to say anything. Taking his
silence as permission, April reached up a little hand and, extending her index
finger, poked at his limp prick. She was rewarded with a slight jump from it
which made her giggle. She began moving her finger over it more quickly, as if
scratching a dog's head. The contact felt like an electric shock running
through Greg's body and he felt himself becoming aroused. "Ooh, it's
getting bigger!" April shrieked excitedly.

Greg closed
his eyes, trying to bury his conflicting emotions as he felt April's finger
caressing his growing member. Suddenly he felt each of her small fingers
encircling his cock and pulling on it. He gasped as he opened his eyes and
looked down. April was grinning widely as she pulled on her brother's dick,
like a child with a new toy. Her bright, blue eyes were flicking back and forth
from the cock in her hand to her brother's half-lidded eyes. "Does it feel
good?" She asked softly.

"Yes," Greg exhaled and nodded his head. Soon he
was rock hard in his sister's awkward but arousing grasp. April stared at it,
her eyes wide. It was nearly nine inches in length and curved slightly to the
right. April's fingers danced across bulging veins along the shaft that she
could barely get her digits around. The engorged head was eye level with April
and was so close it was threatening to poke her. She took her hand away from it
and leaned back admiringly.

"Wow, that is big!" Greg detected a note of
satisfaction in her voice. "The pictures they showed us in health class
didn't look anything like that!"

"I
guess not," Greg said dreamily as he gazed down at his sister. He
couldn't deny she was cute. She was skinny with long legs and ever so slightly
widening hips. Her breasts were still only mere bumps but her erect nipples
stood out clearly against her top which had become dampened by the gathering
moisture in the room. His manhood throbbed almost painfully. "You want to
touch it some more?" He asked her.

"Will it get bigger?" she asked breathlessly.

Greg suppressed a laugh and sheepishly grinned. "No,
but it will feel really good." April shrugged and got up on her knees
again as she grabbed for Greg's protruding member. He sighed as he felt her
warm hand on his length again. He leaned against the sink, his hands gripping
the slick porcelain as he began to buck his hips back and forth with each tug. It
wasn't going to take long for him to cum.

"Oh, what's that?" April asked as she took her
hand of his cock as if it had bit her. Greg looked down and saw her rubbing her
thumb and forefinger together. He saw a clear, sticky fluid there and laughed
softly.

"Oh that's pre cum," he explained to her. "It
does that when it feels really good." April glared at his cock head as
drops of the liquid seeped out the slit at the tip and dropped to the floor. She
rubbed a finger curiously against it, smearing it all around the end of his
purpling head. April pulled her finger away and a string of the stuff followed.
To Greg's amusement April put it up to her nose and sniffed. Then she put it to
her lips and tasted it. Greg's mouth fell open as he watched his sister lick
his pre-ejaculate off her finger. She looked up at him with a surprised look on
her face.

"It
tastes good," she giggled, "sweet." April licked her
finger clean then gripped Greg's shaft once again. The sensation of having his
little sister jerk his cock and seeing her enjoy his pre cum was too much for
Greg. Without warning he felt his cock spasm and shoot out a thick load of cum
that splashed against April's face.

A look of
shock replaced curiosity as April recoiled, taking her hand off the squirting
cock. With a groan, Greg quickly reached down and jerked himself off,
causing more of the thick, sticky fluid to gush out. This time it hit April on
the neck and tank top. "Oh my god!" April yelled in surprise as she
struggled to get up. Greg
continued to pump his cock, coaxing out more cum, some of which fell on April's
scrambling legs.

Greg leaned back against the sink, his hand squeezing the
last drops of cum out of his still stiff member. April grabbed the towel Greg
had gotten from the linen closet and began to wipe the sperm off her body. "Eww,"
April said distastefully. "It's everywhere." Through glazed eyes Greg
saw his little sister strip off her clothing. Before she bounded into the
forgotten shower the images of her puffy, pink nipples and tight, little butt
were burned into his brain.
